Lets not get into the issues of the precision in reading. One thing that can be said, though, about Meiser, is that it releases very little air, but that is also true for the good electronic gauges. The second photo shows the situation of checking pressure in a trailer wheel. It is not possible with Meiser as its head does not fit into the space (I am aware of the vent mismatch, but the head of the Schrader Meiser is of identical size and I already took the photo). However, all is fine with the electronic gauge. Yes, there are plenty of awful electronic gauges around.
